I didn’t know there were such things as chainsaw calluses until Saturday afternoon. It cost me about $35 and a pretty harsh sunburn to find out.Who doesn’t start their Saturday at kickball practice and then stopping by a home improvement store to rent a chainsaw? Someone on the A-J’s Lubbock amateur league kickball team and who needed to remove a small tree and clusters of thick vines from his decrepit fence did. I had four hours to make the most of a Makita electric chainsaw and a whole lot of work ahead of me.
